Answer:
Weight change from place to place because it is a strong function of gravity. Recall that mass is universally constant. Hence weight varies becuas gravity varies. ... Other reason for variation of weight across the earth's surface are, rotation of the earth, altitude and local topography of the area.
Answer:
b) G.P.E = Mgh
300j = M x 10 m/s² x 15 m
300 j/ 10 m/s² x 15 m = M
300j/ 150 s² = M
2kg = M
c) K.E = 1/2 m v²
K.E = 1/2 (50) (50)²
K.E = 1/2 (50) (2500)
K.E= 125000/2
K.E = 625 000 J
